Description

Technical Field

[0001] The invention relates to the field of combination weighers, in particular to a combination weigher for quantitative weighing of noodles. Background Art

[0002] During the noodle production process, after the noodles are made, they need to be weighed according to the specified weight, and then the weighed noodles are packaged to complete the noodle production. In the process of weighing the noodles, a combination weighing scale is often used for weighing.

[0003] Combination weighers generally consist of multiple weighing units with independent feeding structure, weighing structure and discharging structure. The weight in each weighing unit is automatically optimized and calculated using the principle of permutation and combination, and the best and closest combination to the quantitative value is calculated for packaging.

[0004] In current combination weighing machines, noodles typically fall from a feed hopper into a buffer hopper when entering the weighing structure for weighing. The buffer hopper is used to temporarily store the noodles. The buffer hopper's door is then opened to allow the noodles to fall into the weighing structure, and the weight of the noodles is controlled by controlling the buffer hopper's opening time. However, controlling the weight of noodles within the weighing structure solely by the buffer hopper is insufficient when high-precision combination weighing machines are required. Summary of the Invention

[0005] In order to achieve the pre-distribution of the weight of noodles entering the weighing structure and improve the accuracy of the combination weigher, the present application provides a combination weigher for quantitative weighing of noodles.

[0006] The present application provides a combination weighing scale for quantitative weighing of noodles using the following technical solutions:

[0007] A combination weigher for quantitatively weighing noodles, comprising:

[0008] A conveying device, comprising a conveying frame, a retractable belt, and a lower hopper, wherein the lower hopper is arranged above the retractable belt, the retractable belt is mounted on the conveying frame, and the lower hopper stores noodles;

[0009] A material receiving device, comprising a plurality of material receiving hoppers, each of which is located below the retractable belt, into which the noodles fall through the lower hopper and the retractable belt, and wherein a scattering and distributing assembly is provided;

[0010] a weighing device, located below the receiving hopper and used for weighing the noodles;

[0011] The combining device is located below the weighing device and is used for combining and outputting noodles.

[0012] By adopting the above technical solution, noodles fall into the lower hopper from the previous process, and reach the retractable belt through the lower hopper. The retractable belt reaches the top of multiple receiving hoppers through telescopic movement, so that the noodles can enter the receiving hopper, and the noodles are scattered, sorted and pre-distributed by the breaking and distributing assembly, so that some of the noodles can enter the weighing device, and the weighing device weighs the noodles. The weighed noodles are combined and output by the combining device, and then the noodles output by the combining device are sent to the next process.

[0013] By setting up a breaking and distributing component in the receiving hopper, the noodles can be distributed in advance in the receiving hopper, which is beneficial to reducing the weight of noodles entering the weighing device at one time, making it easier to control the weight of the noodles and improving the accuracy of the combination weigher.

[0014] Optionally, the breaking and distributing assembly includes a discharge plate, a valve plate, a pushing cylinder, a baffle plate and a thumb wheel, the discharge plate is rotatably connected to the receiving hopper, the receiving hopper is provided with a vibration assembly for driving the discharge plate to vibrate, the end of the discharge plate is provided with a first comb tooth, the valve plate is provided with a second comb tooth, the first comb tooth and the second comb tooth cooperate with each other, the baffle plate is connected to the receiving hopper, the pushing cylinder is connected to the receiving hopper and is used to drive the valve plate to move toward or away from the baffle plate, the thumb wheel is rotatably connected to the receiving hopper and is driven by a driving motor, the thumb wheel is provided with a plurality of discharge troughs, and the noodles pass through the discharge plate and the valve plate to reach the discharge trough.

[0015] With this technical solution, noodles enter the hopper and fall along the discharge plate. The vibration assembly drives the discharge plate to vibrate, thereby aligning and adjusting the noodles, improving their uniformity. The noodles fall until they are intercepted by the valve plate, where they land on it. The push cylinder pushes the valve plate, along with the noodles, toward the retaining plate. The valve plate abuts the retaining plate and retracts, allowing some noodles to fall into the discharge chute of the dial wheel under the action of its weight.

[0016] Optionally, the scattering and distribution assembly further includes a spring piece and a partition connected to the receiving hopper, the partition can abut against the discharge plate, and the spring piece is arranged above the discharge plate.

[0017] By adopting this technical solution, the partitions intercept the noodles on the discharge plate. When the discharge plate vibrates, a gap is created between the discharge plate and the partitions, allowing some noodles to pass through the gap and reach the end of the discharge plate, achieving initial distribution of the noodles. The provision of springs can also slow the falling speed of the noodles, facilitating vibration sorting and initial distribution of the noodles.

[0018] Optionally, the vibration assembly includes a power motor, an eccentric wheel and a connecting rod, the power motor is connected to the receiving hopper, the eccentric wheel is connected to the output end of the power motor, and the two ends of the connecting rod are respectively rotatably connected to the eccentric wheel and the discharge plate.

[0019] By adopting the above technical solution, the power motor drives the eccentric wheel to rotate, and drives the discharge plate to vibrate through the connecting rod, thereby driving the discharge plate to vibrate.

[0023] By adopting the above technical solution, when the slider and the movable roller move along the sliding groove and the movable frame moves, the driven roller moves accordingly. At this time, the distance between the driven roller and the active roller changes, thereby realizing the extension and retraction of the conveyor belt.

[0024] Optionally, both ends of the conveying frame are rotatably connected to screw rods, the conveying frame is connected to a rotating motor for driving the screw rods, the screw rods are threadedly connected to a moving rod, the conveying frame is provided with a slide groove, the moving rod is slidably connected to the slide groove and is fixed to the moving frame.

[0025] By adopting the above technical solution, the rotary motor drives the screw to rotate, driving the moving rod to move along the slide groove, thereby realizing the movement of the moving frame and driving the extension and retraction of the conveyor belt.

[0027] By adopting this technical solution, noodles flow from the discharge chute of the dial wheel into the temporary storage hopper and then through the discharge port to the weighing hopper. The closing component prevents noodles from falling into the temporary storage hopper / weighing hopper. The weighing component weighs the noodles in the weighing hopper. When the set weight is reached, the discharge port of the temporary storage hopper is closed, preventing the noodles from falling into the weighing hopper.

[0028] Optionally, the combination device includes a conveying member and a combination bucket, the conveying member is used to convey noodles, and the combination bucket is used to collect multiple noodles.

[0029] By adopting the above technical solution, the best combination closest to the quantitative value is calculated through the principle of permutation and combination, the discharge port of the corresponding weighing bucket is opened, and the noodles in the weighing bucket fall into the combination bucket for combination, and are transported to the next packaging process through the conveyor.

[0030] In summary, this application has at least one of the following beneficial effects:

[0031] 1. Noodles fall into the lower hopper from the previous process and reach the retractable belt through the lower hopper. The retractable belt moves through telescopic movement to reach the top of multiple receiving hoppers, so that the noodles can enter the receiving hopper. The noodles are scattered and sorted and pre-distributed by the scattering and distribution assembly, so that some noodles can enter the weighing device. The weighing device weighs the noodles.

The noodles fall to the end of the discharge plate and are intercepted by the valve plate. The valve plate moves toward the retaining plate and retracts after touching it. Some noodles fall into the discharge chute of the dial wheel under the action of gravity, achieving secondary distribution. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following is combined with Figure 1-7 This application is described in further detail.

[0044] The embodiment of the present application discloses a combination weigher for quantitative weighing of noodles. Figure 1A combination weighing device for quantitatively weighing noodles includes a conveying device 1, a receiving device 2, a weighing device 3, and a combining device 4. The conveying device 1 includes a conveyor frame 12, a retractable belt, and a discharge hopper 11. The retractable belt is mounted above the conveyor frame 12, with one end of the retractable belt extending from the conveyor frame 12. The discharge hopper 11 is used to store produced noodles and is connected to the top of the retractable belt. The bottom of the discharge hopper 11 has a discharge opening for the noodles to drop out. The receiving device 2 includes multiple receiving hoppers 21, each located below the retractable belt. The retractable belt extends and retracts to reach above the receiving hoppers 21, and the noodles enter the receiving hoppers 21 through the discharge openings of the discharge hoppers 11. The weighing device 3 is located below the receiving hopper 21 and includes a temporary storage hopper 31 and a weighing hopper 32 arranged above and below for weighing the noodles. The combining device 4 is located below the weighing hopper 32 and is used to combine and discharge the noodles.

[0045] The conveying device 1 includes multiple units, one of which corresponds to multiple receiving hoppers 21, multiple weighing hoppers 32, and multiple combination devices 4. In this embodiment, there are four retractable belts and four lower hoppers 11. Each retractable belt corresponds to four receiving hoppers 21, and the four receiving hoppers 21 correspond to four temporary storage hoppers 31 and weighing hoppers 32.

[0046] The retractable belt includes an active roller 14 rotatably connected to the conveyor frame 12, and the conveyor frame 12 is provided with a drive motor for driving the active roller 14 to rotate. The retractable belt also includes a first auxiliary roller 16, a second auxiliary roller 17, a mobile roller 18 and a driven roller 15 connected by the conveyor belt 13, wherein the first auxiliary roller 16 and the second auxiliary roller 17 are both rotatably connected to the inner wall of the conveyor frame 12, the conveyor frame 12 is provided with a sliding groove 51, and a slider 5 is slidably connected in the sliding groove 51. Both sides of the mobile roller 18 are rotatably connected to the slider 5, the slider 5 extends out of the sliding groove 51 and is fixedly connected to the mobile frame 52, and the driven roller 15 extends out of the conveyor frame 12 and is rotatably connected to the mobile frame 52. The moving roller 18 and the driven roller 15 are connected by the moving frame 52, so that by driving the moving frame 52 to move, the moving roller 18 moves along the sliding groove 51 of the conveying frame 12, and the driven roller 15 moves to drive the end of the conveying belt 13 away from the conveying frame 12 to move closer to or away from the conveying frame 12, thereby realizing the extension and retraction of the conveying belt 13, so that the end of the conveying belt 13 away from the conveying frame 12 can reach above the multiple receiving hoppers 21 in turn, thereby realizing the transmission of noodles to the multiple receiving hoppers 21.

[0047] The conveyor frame 12 is connected to a drive assembly for driving the mobile frame 52 to move, including a screw rod 53, which is rotatably connected to both ends of the conveyor frame 12. The conveyor frame 12 is connected to a rotary motor 54 for driving the screw rod 53 to rotate. The screw rod 53 is threadedly connected to a moving rod 55. The conveyor frame 12 also has a slide groove 56 for sliding the moving rod 55, and the moving rod 55 is connected to the mobile frame 52. The rotary motor 54 drives the screw rod 53 to rotate, driving the moving rod 55 to slide along the slide groove 56, thereby realizing the movement of the mobile frame 52.

[0048] The hopper 21 houses a breaking and distributing assembly for breaking and distributing the noodles into multiple portions. This assembly includes a discharge plate 22 and a partition 71 connected to the sidewall of the hopper 21. Both the discharge plate 22 and the partition 71 are tilted, with the lower end of the partition 71 abutting the upper surface of the discharge plate 22. The discharge plate 22 is rotatably connected to the hopper 21 via a bearing. The receiving hopper 21 is also equipped with a vibration assembly for driving the discharge plate 22 to vibrate. Specifically, it includes a power motor 6, an eccentric wheel 61, and a connecting rod 62. The power motor 6 is fixedly connected to the receiving hopper 21 via a base. The eccentric wheel 61 is connected to the output end of the power motor 6. The connecting rod 62 is rotatably connected to the eccentric wheel 61 via a fisheye bearing. The discharge plate 22 is rotatably connected to the end of the connecting rod 62 away from the eccentric wheel 61 via a reverse-threaded fisheye bearing. The power motor 6 drives the eccentric wheel 61 to rotate, and the connecting rod 62 transmits power to the discharge plate 22 to vibrate. The vibration is used to adjust and organize the noodles, making the noodles more neat. When the discharge plate 22 vibrates, the distance between the discharge plate 22 and the lower end of the partition 71 can change, thereby allowing some noodles to pass through and achieving noodle distribution. A spring piece 7 is also provided above the discharge plate 22. When the noodles fall along the slope of the discharge plate 22, the noodles hit the spring piece 7, causing the spring piece 7 to tilt. The spring piece 7 plays a role similar to a door curtain, which can slow down the falling speed of the noodles, thereby facilitating the breaking up and distribution of the noodles.

[0049] The end of the discharge plate 22 is provided with first comb teeth 74. A bracket is fixedly connected to the inside of the hopper 21, on which a push cylinder 73 is placed. The output end of the push cylinder 73 is connected to a valve plate 72, which is tilted and has second comb teeth 75. The first and second comb teeth 74 and 75 cooperate to prevent interference and collision between the valve plate 72 and the discharge plate 22 during vibration. Furthermore, the valve plate 72 intercepts noodles on the discharge plate 22, allowing them to reach above the valve plate 72 when the push cylinder 73 pushes the valve plate 72 to move. An auxiliary plate is also connected to the output end of the push cylinder 73, positioned below the valve plate 72. The first comb teeth 74 abut the auxiliary plate, thereby limiting the vibration of the discharge plate 22.

[0050] The receiving hopper 21 is also fixed with a baffle plate 24. It is equipped with a dial wheel 23 and a drive motor for rotating the dial wheel 23. The dial wheel 23 is located above the temporary storage hopper 31. Three discharge troughs 25 are evenly spaced on the dial wheel 23, and scraping grooves 26 are formed on the sidewalls of the dial wheel 23. The baffle plate 24 is tilted, with its lower end positioned within the discharge troughs 25. A valve plate 72 abuts the baffle plate 24. The lower end of the baffle plate 24 is equipped with scraping teeth 27 that mate with the scraping grooves 26. As the push cylinder 73 moves, the noodles reach the valve plate 72, which abuts the baffle plate 24 and then retracts. Under the action of gravity, the noodles flow along the baffle plate 24 into the discharge trough 25, achieving noodle distribution. As the dial wheel 23 rotates, the scraping teeth 27 slide within the scraping grooves 26, scraping off some noodles that have not entered the discharge trough 25, keeping the dial wheel 23 clean. As the dial wheel 23 rotates, the noodles in the discharge trough 25 are transferred to the temporary storage hopper 31. The dial wheel 23 is also coaxially connected to a detection disk, which is electrically connected to a counter. The counter is set to count the number of rotations of the dial wheel 23.

[0051] The temporary storage hopper 31 and the weighing hopper 32 are arranged vertically. The inlet of the weighing hopper 32 is located below the outlet of the temporary storage hopper 31. The weighing hopper 32 is connected to a weighing assembly, which detects the weight of the noodles in the weighing hopper 32. The outlets of both the temporary storage hopper 31 and the weighing hopper 32 are equipped with a closing assembly to prevent the noodles in the temporary storage hopper 31 and the weighing hopper 32 from falling. When the outlet at the bottom of the temporary storage hopper 31 is closed, the noodles are temporarily stored in the temporary storage hopper 31. When the outlet of the temporary storage hopper 31 is opened, the noodles fall from the outlet of the temporary storage hopper 31 into the weighing hopper 32. A weighing sensor is installed on one side of the weighing hopper 32 to weigh the noodles in the weighing hopper 32. When the noodles in the weighing hopper 32 reach a set weight, the outlet of the temporary storage hopper 31 is closed, preventing the noodles from falling into the weighing hopper 32. The closing component and the weighing sensor both adopt structures of current technology to achieve the corresponding purposes.

[0052] In this embodiment, the assembly device 4 includes a conveyor 41 and a combination hopper 42. The conveyor 41 is used to convey noodles, and the combination hopper 42 is used to collect multiple noodles. Specifically, the noodles from two adjacent weighing hoppers 32 are first collected by the first combination hopper 42. The noodles collected by the first combination hoppers 42 in the four corresponding rows of units fall into the first conveyor 41. The first conveyor 41 then conveys the noodles into the second combination hopper 42. The second combination hopper 42 collects the noodles and then drops them into the second conveyor 41. The second conveyor 41 is divided into two sections that convey noodles in opposite directions, thereby conveying the two rows of noodles into the third combination hopper 42 in the middle, achieving final collection of the noodles. The collected noodles are then discharged through the third conveyor 41.

[0053] The first transmission member 41, the second transmission member 41, and the third transmission member 41 are all configured as conveyor belts. The first, second, and third combination buckets 42 have identical structural arrangements, each comprising a beam frame, a support plate, and a bucket box, with the bucket box connected to the beam frame via the support plate. Side panels are provided at the front and rear ends of the bucket box, and the lower ends of each bucket box are hingedly connected to a bucket door. The beam frame is hingedly connected to a drive cylinder, and the bucket door is hinged to the output end of the drive cylinder, thereby driving the left and right bucket doors to rotate. When the bucket door and the side panels abut, the bucket door is closed, preventing the noodles in the bucket box from falling. When the bucket door is opened, the noodles in the bucket box can fall onto the conveyor belt for transportation.

[0054] When weighing and packaging noodles, this embodiment has sixteen weighing hoppers 32, each set to a consistent noodle weight. The final noodle weight required for packaging can be calculated as the sum of the noodle weights output by the eight weighing hoppers 32. However, the errors generated by different weighing hoppers 32 vary. To reduce the error in the final noodle weight required for packaging, after the weighing sensor of one weighing hopper 32 measures the weight of the noodles in that hopper 32, the noodles are combined based on the weights of the noodles in the other weighing hoppers 32. The noodles in the weighing hopper 32 that is closest to the final packaging weight are released. The corresponding weighing hopper 32 is then opened by driving a cylinder to release the noodles. The noodles are then combined into a third combining hopper 42 and output from the output end of the third transmission member for packaging. This improves noodle weighing accuracy and efficiency.

[0055] The implementation principle of a combination scale for quantitative weighing of noodles in an embodiment of the present application is as follows: noodles fall into the lower hopper 11 from the previous process, and reach the retractable belt through the lower hopper 11. The rotating motor 54 drives the screw rod 53 to rotate, driving the moving rod 55 to move along the slide groove 56, thereby realizing the movement of the movable frame 52, driving the slider 5 and the moving roller 18 to move along the slide groove 51, and the driven roller 15 moves to drive the conveyor belt 13 away from the end of the conveyor frame 12 to approach or move away from the conveyor frame 12, thereby realizing the extension and retraction of the conveyor belt 13. When the output end of the retractable belt reaches above the receiving hopper 21, the noodles enter the receiving hopper 21.

[0056] After the noodles enter the receiving hopper 21, they fall along the discharge plate 22. The vibration component drives the discharge plate 22 to vibrate, thereby arranging and adjusting the noodles, improving the neatness of the noodles, and slowing down the falling speed of the noodles through the spring piece 7. The gap between the discharge plate 22 and the partition 71 allows some noodles to pass through, realizing the primary distribution; the noodles fall to the end of the discharge plate 22 and are intercepted by the valve plate 72. The valve plate 72 moves toward the material blocking plate 24, retracts after touching it, and some noodles fall into the discharge trough 25 of the dial wheel 23 under the action of gravity, realizing the secondary distribution. The noodles in the discharge trough 25 reach the temporary storage bucket 31 and then reach the weighing bucket 32 ​​as the dial wheel 23 rotates.

[0057] The closing component prevents the noodles in the weighing hopper 32 from falling, and the noodles in the cavity of the weighing hopper 32 are weighed by the weighing component. When the set weight is reached, the discharge port of the temporary storage hopper 31 is closed, so that the noodles in the temporary storage hopper 31 do not continue to fall into the weighing hopper 32. The best and closest combination to the quantitative value is calculated through the principle of permutation and combination, and the corresponding discharge port of the weighing hopper 32 is opened. The noodles in the weighing hopper 32 fall into the combining hopper 42 for combination and are transported to the next packaging process through the conveyor 41.

[0058] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
